Alan Jones talks climate, Paris. Mainstream scientists caught out by Marohasy in Parliament.

Alan Jones pretty much sums up the situation about Christopher Monckton’s prediction last year about Tony Abbott and Stephen Harper. Listen to Monckton from 40 seconds.

“They want $100 billion. In a world that’s broke, swimming in debt…” — Alan Jones

“David King was asked whether all the nations of the world were now, in principle, ready to sign their people’s rights away in such a treaty. Yes, but there are two standouts. One is Canada. But don’t worry about Canada. They’ve got an election in the Spring of 2015 and we and the UN will make sure the present government is removed. He was quite blunt about it.

The other hold out is Australia. And Australia we can’t do anything about because Tony Abbott is in office until after the December 2015 conference. So that means you all have to guard Tony Abbott’s back. Because the Turnbull faction, in conjunction with the UN, will be doing their absolute level best to remove your elected Prime Minister from office before the end of his term and , in particular, before the end of 2015, so that they can get 100% wall-to-wall Marxist agreement. They […]

Scandal Part 3: Bureau of Meteorology homogenized-the-heck out of rural sites too

The Australian Bureau of Meteorology have been struck by the most incredible bad luck. The fickle thermometers of Australia have been ruining climate records for 150 years, and the BOM have done a masterful job of recreating our “correct” climate trends, despite the data. Bob Fernley-Jones decided to help show the world how clever the BOM are. (Call them the Bureau of Magic).

Firstly there were the Horoscope-thermometers — which need adjustments that are different for each calendar month of the year — up in December, down in January, up in February… These thermometers flip on Jan 1 each year from reading nearly 1°C too warm all of December, to being more than 1°C too cold for all of January . Then come February 1, they flip again. Somehow the BOM managed to unravel this bizarre pattern (cue X-files music) and figure out exactly what anti-horoscope-adjustments to use (and they were different in every city). Modestly the BOM did not explain to the public how clever their adjustments were; despite their $300m budget, it took volunteer Bob Fernley-Jones to reverse out the Special Horoscope Cure, and find the square wave algorithm that repaired our damaged climate records. Lucky for the […]

The BOM: Homogenizing the heck out of Australian temperature records

There are adjustments on top of adjustments. Homogenised records are being used to correct raw records. Some man-made adjustments can infect data for miles around…

Rutherglen is a long running station in central Victoria. There are no documented site moves, but the long raw trend of slow cooling was adjusted up to a warming trend. What was cooling of 0.35C per century became a 1.7C warming trend.

Jennifer Marohasy, and others, have spent months trying to get answers from the BOM explaining why these massive adjustments were made. Excuses flowed. In the latest round, the BOM claim the changes are necessary to make the Rutherglen record match the trends in the neighboring stations. What the BOM doesn’t say is that there was no warming in the neighbours either, not until after they were homogenized. The order in which stations are homogenized matters, which rather says something important about the arbitrary nature of the adjustments. Anomalous trends from far distant and poor locations can spread through waves of homogenization until better, longer stations succumb to political correctness and show the “correct” result. Small choices about which stations to to use first in the process can make a huge difference to the […]

Scandal: BoM thermometer records adjusted “by month” — mysterious square wave pattern discovered

There is some major messing with data going on.

What would you say if you knew that the official Perth thermometer was accurate at recording minimums for most of time in October in the eighties, but 0.7°C too warm all of December, and 1.2°C too cool in January? Bizarrely that same thermometer was back to being too warm in February! Try to imagine what situation could affect that thermometer, and require post hoc corrections of this “monthly” nature. Then imagine what could make that same pattern happen year after year. All those weather reports we listened to in Perth in 1984 were wrong (apparently). And this bizarre calendar of corrections is turning up all over Australia.

Bob Fernley-Jones has looked closely at all the adjustments done to achieve the wonderful homogenized ACORN data, as compared to the theoretically “raw” records listed in Climate Data Online (CDO) on the BOM website. He can’t know what the BOM did (since they won’t tell anyone), but he knows the outcome of their homogenization. He was shocked when he noticed a strange square-wave pattern repeating year after year; he was astonished that there were corrections calendar month by calendar month, up and down, switching […]

A mess of adjustments in Australian capital cities — The inexplicable history of temperatures

Two out of three Australians live in our capital cities where the longest and best resourced temperature records would be found. These are the places where the weather reports matter to the most people on a daily basis — and where headlines about records and trends will be widely discussed. But these are also the sites which have been affected by the growth of concrete and skyscrapers, and potentially have the largest urban heat island (UHI) effect, so might need the largest adjustments.

Bob Fernley-Jones has been going through the BOM records for six of Australia’s state capitals, looking at the original raw data (at least, as is recorded in the BOM’s climate data online, called CDO). Bob compares the new “corrected” dataset called ACORN for these locations — that’s the all new marvelous adjusted data. He finds many step changes that can’t be explained by known site moves or the UHI effect. Many step changes occur in either minima or maxima, but not in both at the same time, which is also odd. As we already know, the adjustments usually cool the past — especially the minima (see all the blue lines on graphs below […]

Not a 100% believer? Even borderline climate apostates like Pielke must be punished in the witchhunt

The witchhunt over tenuous connections to fossil fuel funding wants to do a lot more than just silence a few people. The aim is to maintain the global chill over all of academia. That’s why it’s so important we support the individuals under fire, and don’t give in.

Congratulations to Richard Lindzen, John Christy, Judith Curry, Steven Hayward, Roger Pielke, David Legates, and Robert Balling. All of them have been named to be investigated and lined up for character assassination like Willie Soon. Obviously they are effective and convincing speakers, and a threat to the climate-industry.

Stephen Hayward is flattered, and mocks the critics: “Are You Now or Have You Ever Been a Climate Skeptic?”

“Let’s start by axing a simple question: If I say “two plus two equals four,” does the truth of that proposition depend on whether I’ve received a grant from the Charles G. Koch Foundation? Apparently it does for Rep. Raul Grijalva (D-AZ), the ranking member of the House Committee on Natural Resources. He has sent letters to seven universities targeting seven academics who, according to the Democratic spokesman for the committee, were chosen because they seem “to have the most impact on policy in the […]

Category Five storms aren’t what they used to be

UPDATE: Data for Middle Percy Island has disappeared from the BOM site, but Jennifer Marohasy kept a copy. (I’m sure the BOM will be grateful!) The Courier Mail has an article quoting Jennifer.

The facts on Cyclone Marcia: the top sustained wind speed was 156 km and the strongest gust 208 km/hr. These were recorded on Middle Percy Island in the direct path before it hit land and apparently rapidly slowed. The minimum pressure recorded after landfall was 975Hpa. BOM and the media reported a “Cat-5” cyclone with winds of 295 km/hr. To qualify as a Cat 5, windspeeds need be over 280km/hr. The UN GDACS alerts page estimated the cyclone as a Cat 3.

The damage toll so far is no deaths (the most important thing), but 1,500 houses were damaged and 100 families left homeless. It was a compact storm, meaning windspeeds drop away quickly with every kilometer from the eye, so the maps and locations of the storm and the instruments matter. See the maps below — the eye did pass over some met-sites, but made landfall on an unpopulated beach with no wind instruments. It slowed quickly thereafter. The 295 km/hr wind speed was […]

Satellites show 2014 was NOT the hottest ever spring (or winter or summer or autumn) in Australia.

The headlines are burning around the nation: 2014 was the hottest ever spring! Except it wasn’t. The UAH satellite coverage sees all of Australia, day and night, and are not affected by urban heat, airport tarmacs, “gaps in the stations”, or inexplicable adjustments.

When will the Bureau of Meteorology discover satellites? How many years will it take to train the ABC journalists to ask the BOM if satellite measurements agree or disagree with their highly adjusted, altered, deleted, and homogenised ground stations?

I used exactly no tax dollars to email John Christy of UAH, get the latest data, and graph it to show that in Australia 2014 was not the hottest spring, and not the hottest winter, summer or autumn either. Why can’t the BOM or the $1.1 billion ABC do that?

The obsession with cherry picked, unscientific and irrelevant single season records that are not even records shows how unscientific the Bureau of Met is. By its actions we see a diligent PR and marketing agency. If the BOM served the public, they would make sure the public knew that these records depend entirely on their choice of dataset and on their mysterious homogenization procedures. If the BOM were […]

Under pressure, Australian BOM puts up facade of “transparency” — too little, too late

Bottom line: The BOM has added a page listing “Adjustments”. It’s two years late, inadequate and incomplete. Skeptics shouldn’t have had to ask for it in the first place, and we still don’t have the algorithms and codes, or rational answers to most questions. No one can replicate the mystery black box homogenisation methods of the BOM — and without replication, it isn’t science. There is still no explanation of why an excellent station like Rutherglen should change from cooling to warming, except for vague “statistics”, or why any station should be adjusted without documentary evidence, based on thermometers that might be 300 km away.

Lo and behold, the pressure from The Australian and independent analysts means the BOM has made a weak belated attempt to do what it has implied it always has done. When Michael Brown provided cover for the BOM he said the notion that scientists were hiding data was “pseudoscience”. The BOM, meanwhile, added a page called “Adjustments”, two years after launching “ACORN”, quietly admitting that the skeptics were right. They did not correct Brown’s baseless namecalling. Other apologists for their inexplicable anomalies, major adjustments or errors — like David Karoly — demand the […]

The lost climate knowledge of Deacon 1952: hot dry summers from 1880-1910

Once upon a time, Australian climate scientists discussed and published climate trends of the late 1800s. And lo, the long lost hot weather decades were apparent in many places in inland South Eastern Australia. While skeptics are accused of cherry picking data from Bourke, Rutherglen and Deniliquin, there are plenty of other examples. In the last post, the 1953 Argus story described hotter drier summers in Omeo, Bendigo, Hay, Bourke, Alice Springs, Echuca, Albury, and Cooma. Here is a Deacon et al peer reviewed graph of the long term trends at Hay, Narrabri, Bourke and Alice Springs.

Thanks to Chris Gillham for finding the Deacon paper of 1952. [On another point, I’ll have a response up to the new BOM “adjustments” page later. In short, their data still has many inexplicable errors like where maxima are lower than minima, and they are still not providing all the details we need to replicate their data and homogenization methods. – Jo]

But just have a look at this graph. Degrees Fahrenheit of course. State of the art, 1952.


These cooling trends cover “only” a couple of million square kilometers of Australia:

The location of Alice Springs, Bourke, Narrabri, and […]

BOM homogenisation in Deniliquin creates discontinuities and changes trends

The list goes on, and there is more to come.

In Deniliquin NSW, the homogenisation has lifted both the maxima and minima trends — again converting cooling to warming.

Graham Lloyd continues to increase the pressure on the Australian Bureau of Meteorology. In answers to Lloyd the BOM could only defend their work with the extraordinary statement that while some trends at individual stations look anomalous, overall the results “showed a similar warming trend to that of other inter­national climate ­organisations. ”

So they inadvertently admit that they expect Australian trends to look like trends in other parts of the world. Despite the fact that Australia is drier, flatter and surrounded on every edge by oceans, the Bureau would consider it a fail if our trends were different to others? We’re in the opposite hemisphere to many international climate organizations, which may or may not matter, but we’ll never find out if we are trying to fit our data to theirs. And El Nino’s and La Nina’s mean very different things to countries on opposite sides of the Pacific. We’re blurring the resolution from thousands of data-points. The raw data is blended not just on regional scales but thanks […]

Pitman says BOM don’t “fiddle” with data — it’s magical science by Elite Centres of Excellence

What is striking about Andy Pitman and Lisa Alexander’s response to the articles in The Australian, on The Conversation, is how intellectually weak it is, and how little content they have after we remove the logical fallacies. It’s argument from authority, circular reasoning, and strawmen. Hail the Gods (and don’t look over there)! They don’t question Jennifer Marohasy’s remarkable figures, they don’t even mention them at all, nor use the names “Rutherglen”, “Amberley” or “Bourke” –how revealing.

And these are the points at issue. Long cooling trends at supposedly excellent sites had been homogenized and transformed into warming trends. Rutherglen is the kind of station other stations dream to be: it has stayed in the same place according to the official documents, isn’t affected by the heat from urban growth either and is similar to its neighbors. Other stations might be adjusted to be more like it. Instead the BOM has a method that detected “unrecorded” site moves at Rutherglen by studying unnamed stations somewhere in the region. Awkwardly, someone who used to work there says the thermometer didn’t move. Hmm. Would a thinking person ask for more details and an explanation? Not if you are director of an ARC […]

Hiding something? BOM throws out Bourke’s hot historic data, changes long cooling trend to warming

Hello Soviet style weather service? On January 3, 1909, an extremely hot 51.7C (125F) was recorded at Bourke. It’s possibly the hottest ever temperature recorded in a Stevenson Screen in Australia, but the BOM has removed it as a clerical error. There are legitimate questions about the accuracy of records done so long ago — standards were different. But there are very legitimate questions about the BOMs treatment of this historic data. ‘The BOM has also removed the 40 years of weather recorded before 1910, which includes some very hot times. Now we find out the handwritten original notes from 62 years of the mid 20th Century were supposed to be dumped in 1996 as well. Luckily, these historic documents were saved from the dustbin and quietly kept in private hands instead.

Bourke has one of the longest datasets in Australia — but the BOM, supposedly so concerned about the long term climate trends, appears to have little curiosity in the hot weather of the 1880’s and 1890’s (I talked about the amazing heatwave of 1896 here where hundreds died and people in Bourke escaped on special trains). If it had been a cool spell then, would the BOM feel […]

ABC invites BOM and Marohasy to speak — BOM decline, Marohasy accepts, but is cut off?

Bronwen O’Shea, ABC

UPDATED: Correction. The interview was done by a fan of John Cook, not John Cook. Notes in the post and apologies. – Jo

Hm, curious event on the ABC today. Credit to Bronwen O’Shea, host of the ABC morning radio program for the Goulburn Murray, for asking both Jennifer Marohasy and the BOM to discuss the Rutherglen temperature adjustments. Good-o, I say — public debate and answers! (Note that link is just to their website, I have not found a copy of the interview or transcript).

But everything worked against the ABC. First the BOM chose not to even try to answer. (Hm?) Then not long after the interview started, the line suddenly went dead and Marohasy was abruptly cut off. She waited for the call back, but it never came. What bad luck eh? Even more unlucky — when the ABC tried to call her back they got a fan of John Cook on the phone instead*. Then, things got even worse for poor ABC listeners — because the fan of Cook mistakenly thought Rutherglen was different to the surrounding stations, but the BOM raw records say otherwise (see the graph below). UPDATED: Apologies to […]

BOM finally explains! Cooling changed to warming trends because stations “might” have moved!

It’s the news you’ve been waiting years to hear! Finally we find out the exact details of why the BOM changed two of their best long term sites from cooling trends to warming trends. The massive inexplicable adjustments like these have been discussed on blogs for years. But it was only when Graham Lloyd advised the BOM he would be reporting on this that they finally found time to write three paragraphs on specific stations.

Who knew it would be so hard to get answers. We put in a Senate request for an audit of the BOM datasets in 2011. Ken Stewart, Geoff Sherrington, Des Moore, Bill Johnston, and Jennifer Marohasy have also separately been asking the BOM for details about adjustments on specific BOM sites. (I bet Warwick Hughes has too). The BOM has ignored or circumvented all these, refusing to explain why individual stations were adjusted in detail.

The two provocative articles Lloyd put together last week were Heat is on over weather bureau and Bureau of Meteorology ‘altering climate figures, which I covered here. This is the power of the press at its best. The absence of articles like these, is why I have said the media […]

The heat is on. Bureau of Meteorology ‘altering climate figures’ — The Australian

Congratulations to The Australian again for taking the hard road and reporting controversial, hot, documented problems, that few in the Australian media dare to investigate.

How accurate are our national climate datasets when some adjustments turn entire long stable records from cooling trends to warming ones (or visa versa)? Do the headlines of “hottest ever record” (reported to a tenth of a degree) mean much if thermometer data sometimes needs to be dramatically changed 60 years after being recorded?

One of the most extreme examples is a thermometer station in Amberley, Queensland where a cooling trend in minima of 1C per century has been homogenized and become a warming trend of 2.5C per century. This is a station at an airforce base that has no recorded move since 1941, nor had a change in instrumentation. It is a well-maintained site near a perimeter fence, yet the homogenisation process produces a remarkable transformation of the original records, and rather begs the question of how accurately we know Australian trends at all when the thermometers are seemingly so bad at recording the real temperature of an area. Ken Stewart was the first to notice this anomaly and many others when he compared […]

Wow, look at those BOM adjustments – trends up by two degrees C!

The mystery of Australian temperature adjustments

Ken Stewart has been checking the Australian BOM official ACORN minima data against the raw data. This week he highlights the six very strange cases of Brisbane Airport, Amberley RAAF, Dubbo, Rutherglen, Rabbit Flat, and Carnarvon. In all these places the adjustments change the trend by more than 2 whole degrees C. It’s a kind of hyper-homogenization.

Thermometers are supposed to be accurate to a tenth of a degree. Australian average trends are sometimes calculated to one hundredth of a degree. What then do we make of adjustments that change the trends by a whopping 2 degrees, and decades after the data came in? The only thing we know for sure about Australian temperatures is that we need an independent audit. Why is it left to volunteers to check? Surely the Greens want good data too?

Some of these stations are isolated outposts, so theoretically they are the heavyweights on Australian area-weighted averages. The map scales can be a bit deceptive. In outback Australia the nearest neighbours can all be 500 km away (300 miles). Some dots on the map are not so much a town as a motel and a gas station. […]

The message from boreholes

There have been suggestions that Jo Nova might be trying to hide or ignore the most recent boreholes graph from Huang et al. So here it is. This is the last 2,000 years according to 6000 boreholes, with the last 100 years also using the “instrumental record” which gives us that hockey-stick uptick at the end. Below I explain the pros and cons of this study and update my thoughts.

Huang and Pollack 2008: Their latest boreholes published study


A borehole sounds like a bit-of-a-stretch as a proxy. How could we tell if the world was warmer in 1066 by drilling a hole in the ground? Yes, fair point. But what makes boreholes useful is that they are global and there is a lot of data: specifically 6,000 holes all over the world.

I’ve been looking at boreholes in more detail, analyzing them in the light of newer proxies. When all the evidence is considered, boreholes turn out be not-much-use at giving us meaningful numbers in degrees C, and in my opinion, not-too-hot at telling us the “when” of an event either. Too much depends on assumptions.

But what are they good for is that, when combined with […]

Australia’s High Quality Data: 12-year-sites used for “long term” trends


What would you say if you knew our high quality temperature record included sites with 100 year long “records” which were based on just 12 years of data and some undisclosed method was used to construct 90% of the graph?

Wow? I mean, Wow?! Why are these sites with such little actual data being included in a series called “high quality”?

Presumably the “adjusted” trends were recreated (in a sense) by homogenizing data from nearby stations, but why not use just the stations with long records in the first place? Out in the vast outback there are long distances between stations, and while a “splice” might overlap for ten years, who knows whether the dramatic PDO oscillations don’t shift weather patterns during their 30 year cycle and mean that any ten year period is not indicative of the longer time frame.

BOM compensate for the Urban Heat Island effect by making adjustments that essentially result in almost no change in the trend. They remove the “urban” stations, but UHI affects even small populations, and Andrew Barnham speculates that the largest changes in the UHI effect may occur in these smaller rural locations that are still included.

Andrew […]

New Zealand – Where did that warming go?

UPDATED (below)

Think of this as a car crash. NIWA says: “The car’s fine, there’s nothing wrong with it.”

Then: “We can’t find the keys (actually we’ve lost the car)”.

Later: “We weren’t driving it”.

Finally: “The car doesn’t exist”.

There’s a litany of excuses. The National Institute for Water and Atmospheric Research (NIWA) claims New Zealand has been warming at 0.92°C per 100 years. But when some independent minded chaps in New Zealand graphed the raw NZ data, they found that the thermometers show NZ has only warmed by a statistically non-significant 0.06°C. They asked for answers and got nowhere, until they managed to get the light of legal pressure onto NIWA to force it to reply honestly. Reading between the lines, it’s obvious NIWA can’t explain or defend the adjustments.

Richard Treadgold was one of that team and wrote it up here.
